SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 695,706, dated March18, 1902. Application filed February 14, 1901. Serial No. 47,311. (N0model-l T0 aZl whom, it may concern:

Be it known that I, EMIL BOMMER, a citizen of the United States,residing in New York, borough of Brooklyn, in the State of' New York,have invented certain new and useful Improvements in Spring-Hinges, ofwhich the following is a Specification.

This invention relates to improvements in spring-hinges,and moreespeciallytoimprove ments 1n the spring-hinges known as boX- flangedspring-hinges, which are applied to the marble, slate, or otherpartitions of waterclosets, for the purpose of supporting the door whenclosed flush with the front edge of the partition; and the inventionconsists of a spring-hinge in which one flange is applied to the door,while the other flange is made box-shaped in one piece with the barrelof the spring-hinge and provided with means whereby the hinge can beadjusted to a partition of any thickness.

The invention consists, further, of a boxflanged spring-hinge in whichthe box-flange is made in one integral piece with the barrel of thespring-hinge, the box-flange being formed by the extensions of the edgesof the barrel, which are riveted together at the back portion of thebox-flange, aswill be fully described hereinafter and finally pointedout in the claims.

In the accompanying drawings, Figure 1 represents a perspective View ofmy improved box-flanged spring-hinge. Fig. 2 is a rear elevation of thesame. Fig. 3 is a top view. Fig. 4 is a horizontal section on line 4 4,Fig. 2; and Fig. 5 is a plan of the blank from which the barrel andbox-flange are made.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A indicates the barrel of a spring-hinge, andB one flange of the same, which is provided with perforated ears I),that are bent up at right angles to the upper and lower edges of theflange B and with a stop-flange b, that connects the perforated ears, asshown clearly in Fig. l. The

perforated ears are retained on the springbarrel of the hinge betweenthe ball-shaped terminals B of the pintle D and the pintlesockets C. Thebarrel A is made integral with the second flange E of the hinge, whichis made in-the form of a box-flange of approximately U shape, the outerportion of The spring-barrel Aand the box-flange E are stamped up bymeans ofdies from one piece of sheet metal in the form shown in Fig. 5.I One edge of the spring-barrel is connected with the back and outerportion of the box-flange,while the opposite end is connected with theinner portion of the box-flange, the middle portion f being cut out andbent over upon the body of the box-flange and connected thereto byrivetse, as shown in Figs. 1, 2, and 4.-. The

upper edges of the'inner portion of the boX- flange adjacent to thespring-barrel have extensions e, which are connected by rivets e to theback of the box-flange, so that thereby a rigid connection of thebox-flange with the barrel is obtained. The portion of the boxflangeadjacent to the barrel, comprisingthe extensions 6 and 6*, may insteadof being made integral be made of an independent piece of metal bent inproper shape and riveted to the back of the box-flange.

The ad vantages of my improved box-flanged spring-hinge are that a morereliable connection of the'barrel and box-flange is obtained than whenthe barrel and flange are made up of separate pieces and connectedtogether; secondly, that the expense of manufacture is much reduced,while at the same time a stronger hinge is produced; thirdly, that thehinge is adapted to be applied to various thicknesses of partitions, theouter portion of the box-flange being adjustable to partitions ofvarious thickness by changing the curvature of the partially-circularportions f. The flanges of the spring-hinge, with the spring-barrel, canbe struck up in one piece, by means of dies, from sheet metal, so thatsheet metal is used in place of cast metal for the manufacture of thesehinges, and thereby a box-flanged spring-hinge of'approximately the samestrengthv as similar spring-hinges made of cast metal and one which isbetter adapted to the Various requirements of the trade is produced.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A spring-hinge for hanging doors to marbio andother partitions, provided with a spring-barrel, a flange havingperforated ears bent over at the upper and lower edges of the barrel, abox-flange made integral with said spring-barrel, and partially-circularportions connecting the outer leaf and the back of said box-flange,substantially as set forth.

2. A spring-hinge for hanging doors to marble and otherpartitions,c0nsisting of a springbarrel, pintle-sockets at the upper andlower EMIL BOMMER.
